Abstract: The Karnafuli Hydroelectric Project is located in Bangladesh. On August 13, 1961, distress was noted in the spillway flow. A special Board of Consultants considered possible causes for the chute damage, such as: uplift pressure from seepage, uplift pressure under the pavement having origin in the difference in head over the drainage eductors in the dentates and on the surface of the pavement, i. e. tailwater uplift, and impact of logs. The St. Anthony Falls Hydraulic Laboratory was authorized in 1962 to conduct studies of the spillway. This paper discusses the study methods, hydraulic models, and results.
